I have adapted t.c.s.cftp and one of the ssh examples to transfer files to a
remote host and than execute some commands there.
Both has to be done for several remote hosts in sequence.
Start of the ssh session has to wait until the cftp sessions are complete and
after that has completed, the cftp session for the next host has to be started
. . .
The cftp part begins so:
def distributeStuff(host, tasks):
. . .
doConnect(reactor, options, tasks)
def doConnect(reactor, options, tasks):
. . .
conn.tasks = tasks
vhk = verifyHostKey
uao = SSHUserAuthClient(options['user'], options, conn)
connect(host, port, options, vhk, uao).addErrback(_ebExit)
class SSHConn(connection.SSHConnection):
def serviceStarted(self):
self.openChannel(SSHSession())
I played with inlineCallbacks but could not find a point where to place my
yielded function.
I tried to overwrite channelClosed in SSHConn:
def channelClosed(self, channel):
super(SSHConn, self).channelClosed(channel)
if len(self.channels) == 0:
print ‚[Last channel closed.]'
# open ssh ssession:
. . .
but that gave an unhandled error:

Please advise!
